E. C. powder

In Great Britain they are frequently referred to as E.C. powder (this stands for Explosives Company, one of the early manufacturers in England). In the U.S.A. they are usually referred to as bulk powder, probably because they were loaded in bulk, volume for volume, with blackpowder. 

According to U.S. Army Specification No. 50-13-8B E.C. powder should pass two tests [31]. 

Schultze powder and E. C. powder are known as bulk sporting powders, either because they are loaded by bulk or because, for the same bulk, they have about the same power as black powder. Bulk powders burn quickly. They are used in shot guns, in hand grenades, in blank cartridges, and occasionally in the igniter charges which set fire to the dense colloided propellent powder which is used in artillery. 

Uses In place of potassium chlorate in percussion primer compositions, with the object of prodneing noncorrosive primers, P4. Also in pyrotechnic compositions, in blasting explosives, and in some componnd propellants. See Double-Base Powders, E. C. Powder, Poudre B. N., Tonite, Strontium Nitrate, F8.

B. Schultze Powder, E.C. Powder, Collodion-Cotton, c.—The sample is dried in the oven as above for fifteen minutes, and exposed for two hours to the air. The test as above for compressed gun-cotton is then applied. 

E.C. powder consists principally of nitro-cellulose mixed with barium nitrate and a small proportion of camphor. 

Plastics used for fluidised bed powder coatings include polyethylene, p.v.c., nylon, p.v.f.2, p.e.c.t.f.e. and a variety of polyolefins and their copolymers.

Group C powders are of small particle size, cohesive by nature and hence, difficult to fluidize. Either the fluidized bed lifts as a solid plug of material or forms stable channels of air flow, which allows the fluidizing gas to escape. The latter phenomenon is referred to simply as channelling . It may be possible to fluidize such powders by mechanical agitation (e.g., stirring, vibration).

Of importance in catalytic studies, is that the anisotropic nature of the recoil-free fraction can be deduced also for samples where the orientation of the surface is not known (e.g., powdered samples), as noted earlier (Section I, C, 5). In this case, the recoil-free fraction is not measured directly, but its...
